Interesting read on Netflix's security alert system. There is also a link in the comments to a video as to why Netflix built their own system instead of using COTS (Commercial Off The Shelf). https://www.youtube.com/watch?v=qzK9Mj2V6BA I haven't watched the video yet, but it is on my ever growing list.

Wow! This should be interesting. I've been following Nest for a couple of years now and find their Thermostat and Smoke Detector pretty cool. A little pricy, but defiantly cool. This can only improve things.#Nest
